What do you mean by VoIP security? SIPS/SRTP?

VoIP has so very many security issues as to be almost laughable. There are so
many VoIP issues that I would not know where to begin -- ranging any where from
MiTM (ARP spoofing, capture and replay, etc.) and authentication and
authorization, to RTP injection and ... I could go on forever, almost.

Bottom line: VoIP, as implemented today, is a clear-text protocol (unless you
are tunneling SIP and RTP through IPSec). It has all the equivalent security
issues of any clear text protocol, such as FTP (actually, TFTP may be a better
comparison).

If you should be one of the rare organizations using SIPS/SRTP, there are still
a ton of security issues (for example, SRTP setup in the clear). There are also
incredible interop issues if you are using SIPS/SRTP.

I just finished a 9 month VoIP project. I can assure you that VoIP security is a
major nightmare. It is *not* a pretty picture! For a decent introduction to the
low hanging fruit of VoIP security, I recommend:
http://www.amazon.com/Hacking-VoIP-Protocols-Attacks-Countermeasures/dp/1593271638/ref=sr_1_5?ie=UTF8&s=books&qid=1255539821&sr=1-5

I Hope this helps!

Hello Abhishek,

You can read through this article, though old, still worth reading:
Article: www.cisco.com/asiapac/ipc/files/miercom_report_voip_security.pdf

There are lot of tools available for VoIP Security Assessment and
testing. You can find a list of those tools here:
List 1: http://www.security-database.com/toolswatch/+-VoIP-+.html
List 2: http://www.voipsa.org/Resources/tools.php

Also you can have a look at this thread: VoIP Security Assessment Tools
Thread: http://www.voipsa.org/pipermail/voipsec_voipsa.org/2006-March/001251.html

Besides these, just recently a VoIP Security Live Distro was released.
The distro includes VoIP security assessment tools such as UCsniff,
VoipHopper, Videojak, videosnarf, ACE, Warvox, and a number of other
useful tools along with traditional security assessment tools like
Metasploit, Nmap, Netcat, Hydra, Hping2 and others.
More Info: http://vipervast.sourceforge.net/

Hope this helps!!

Really very helpful suggestions and resources.

Actually I have been given a task to write 2-3 page writeup on VoIP
Security and how we can do VoIP
security assessment.

Depends on what your goal(s) is/are. For example, snooping
(eavesdropping) is accomplished by sniffing the wire and recompiling the
audio (RTP or other protocol used
http://www.ietf.org/rfc/rfc3550.txt?number=3550) which would affect
confidentiality. With any kind of packet injection tool and knowledge of
SIP (if SIP is targeted) you could do some interesting things. Because
most VoIP equipment are using a client server set-up and almost ALL VoIP
based phones have a web interface, they're DoSable, prone to the same
attacks as any other HTTP server.

Imagine the following: Using curl being able to reset variables. Not a
big deal at first glimpse, however imagine this:

Scenario1: You change your caller ID as that of an employee. Call IT and
tell them "reset my X (voicemail, email, etc.) password" Because the IT
guy wants to validate you he uses caller ID and does so.
Scenario2: You change your caller ID as that of an employee. Call IT and
tell them "reset my X (voicemail, email, etc.) password" Because the IT
guy wants to validate you he refuses to use caller ID and tells you he
will call you right back. At this point if you DoS'd the phone it
wouldn't receive calls hence them going into voicemail. In comes perl,
curl or whatever packet builder you prefer... Perform a POST to the
phone or server, depending on your craftiness and time, reset the
voicemail PIN. Go into the user's voicemail, instant pentesting
gratification.

There are plenty of ways to abuse VoIP - the facts are facts though -
it's just data. From a sniffing/PITA perspective, you could snoop calls,
splice together audio and create your own soundboard WITH that person's
voice - perhaps bypassing voice recognition. Sky's the limit when you
have a focus on what it is you want to do. So ask yourself that first...
What is it you want to do... Capture data, manipulate data, etc.

I know quite a few revisions of firmware on certain phone vendors that I
can re-write POSTS and reset phones, passwords, change names, insert a
call forward argument. It all boils down to what is it you're trying to
accomplish. In the case of an assessment, the approach for me would be
to start at the ground up. Test the security of the phone application
itself (HTTP scanner), test if any ports are open and why - which means
you'd have to have literature from the manufacturer, test the
tamperability of the connection (can you sniff the wire, any vlans (VLAN
hopping), can you perform posts/injections, etc). Follow the same steps
you would for any client server.

I am pretty new to the list and just wanted to let everyone know that
I have developed a VoIP security live distribution called VAST. The
distro includes VoIP security assessment tools such as UCsniff,
VoipHopper, Videojak, videosnarf, ACE, Warvox, and a number of other
useful tools along with traditional security assessment tools like
Metasploit, Nmap, Netcat, Hydra, Hping2 and others. The link for the
distro is http://vipervast.sourceforge.net. The distro is still in a
very beta stage and suggestions are welcome.

As the other guys mentioned, it is really a huge topic. You may want
to start looking at the two main protocol SIP and H.323. A quick
search on securityfous will give you quite a big list of SIP and H.323
testing articles. A quick list of tools i can think of

SIP Proxy - http://sourceforge.net/projects/sipproxy/
SFTF - http://www.sipforum.com/index.php?Itemid=&option=com_search&searchword=framework
SIP Bomber - http://freshmeat.net/projects/sipbomber/
Another list of tools from VOIPSA - http://www.voipsa.org/Resources/tools.php

regards,
Rick

I've said this story once and I will repeat it.

Should I go into my local Sears or a similar store, get ahold of all the
tools associated with fixing an engine and perform the duties of trying
to do so without having an iota's worth of knowledge about the
components of an engine?

The tools mean nothing if a person doesn't understand what they're doing
with them, how they work and why sometimes you might not need a hammer
when you have the back of a strong wrench to nail something in.
